Can’t make it any better. Easiest way to customize and use all the weather models. Great work.
Best weather app
estebamba
Truly a great app - you can tell the developper is doing this not for $ but because they care before anything about functionnality. Great for people who want to know (and see) weather (and weather systems) and forecasts at a glance.
Perfect weather app
Mr.Foreman Momo
This is a great app that provides all the data you need for predicting the weather. A widget would make this app 11/10!
Great app!

The design of this app is fantastic - intuitive, visual and interactive - nothing else like it on the App Store. Well done!
Release 4.649 (15 Oct 2026)
=====================
New MEPS Nordic Model, faster downloads
- New model in Gold Pro: MetCoOp MEPS 2.5 km for the Nordics and the Baltics. It has 1-hour steps out to 66 hours, and a new forecast every 3 hours. It was built together by Norway, Sweden, Finland, Estonia and Latvia.
- Faster downloads: the map fills in about twice as fast. You can turn this off under Improved Downloads in Advanced Settings.
- Colour scale editor: Cut now only hides the end of the scale, and the new Push squeezes the colours.
- Now in Hungarian and Romanian, and missing translations are filled in.
- Fixed a layout editing bug.
- Fixed two crashes.
- Updated the sun and moon, the colour picker and a few libraries. Watch out for bugs.
